## Hybrid cryptosystems
[Hybrid cryptosystems](https://en.wikipedia.org/wiki/Hybrid_cryptosystem) combine two cryptosystems and make use of their respective advantages:
[Hybrid cryptosystems](https://en.wikipedia.org/wiki/Hybrid_cryptosystem) merge the strengths of two distinct cryptosystems, capitalizing on their respective advantages:
- A public-key cryptosystem is used to safely handle shared secrets over insecure channels (in OpenPGP: so-called "session keys")
- A symmetric-key cryptosystem is used to efficiently encrypt and decrypt long messages (using an OpenPGP "session key" as the shared secret)
- Public-key cryptosystem: used to securely exchange shared secrets, known as "session keys" in OpenPGP, across insecure channels
- Symmetric-key cryptosystem: used to efficiently encrypt and decrypt long messages, leveraging an OpenPGP "session key" as the shared secret
